# yuthavithi bb scalper V2

‎2680‎ مشاهدة
This is a trend based BB scalper. I notice when the trend is fading and the price is going to leave the upper/lower band, the opposite band will stop expanding and turn back. This can serve as a good point for profit taking.

Like my previous force scalper, this scalper also use ATR to filter sideway period. It will provide buy/sell signal only when the price is trending.

sideway period is indicated by the silver upper/lower band, it does not trade during this period. but provide close signal instead.
